There are useful for off-loading work to a different threading context, for delayed processing, or for serializing activities. diff --git a/Documentation/NuttxUserGuide.html b/Documentation/NuttxUserGuide.html index 26079b5752e..4e028ae0bdd 100644 --- a/Documentation/NuttxUserGuide.html +++ b/Documentation/NuttxUserGuide.html @@ -9731,37 +9731,6 @@ notify a task when a message is available on a queue. }; -
